River Rock Pebbles | Used with Pebble Bond Epoxy

SURFACE PREPARATIONS:

All surfaces must be dry, clean and free from grease, oil or foreign matter.

MIXING INSTRUCTIONS:

Pebble Bond Epoxy is a three to one ratio. Important: DO NOT VARY FROM THIS MIX RATIO.

1. Place one quart of cure in container ,add three quarts of resin. (USE SEPARATE MEASUIRN VESSELS FOR EACH COMPONENT)
2. Mix for two minutes with a flat stirrer, scraping the sides to ensure proper mix. Let stand while loading mixer.
3. Pour into mixer, 150- 180 pounds of stone (depending on the size of stone)
4. Run mixer approximately three minutes until stone is thoroughly statured with Pebble Bond Epoxy

APPLICATION INSTRUCTIONS:

Refer to batch mix sheet for correct ratio of aggregate to epoxy.

1. Remove the mix to the wheelbarrow and dump into place
2. Immediately spread with rake to the correct level
3. Trowel smooth and tight. IMPORTANT: loosely troweled stone will cause a weak system. Use Trowel Slick as a trowel lube and AVOID excessive amounts on trowels or deck.

CLEANING:

Tools may be cleaned with soap and water immediately after application. NOTE: If tools are not cleaned within one half hour after being used, it will be virtually impossible to remove the Pebble Bond Epoxy from your tools.

SAFETY PRECAUTIONS:

All epoxies, including Pebble Bond, have the potential of causing dermatitis on people who are sensitive to epoxy. Users are cautioned to exercise due care, taking care not to get on skin, clothes or in eyes. If splashed in the eyes, flush repeatedly with warm water for at least fifteen (15) minutes and call a physician immediately.

PLEASE NOTE:

Recommended thickness for the river rock surface is : 1/2 inch thick for pools, decks, patios, and walkways. For driveways, the river rock should be 3/4 inch thick.

IMPORTANT:

If the temperature is below 60F, COLD WEATHER RESIN MUST BE USED

BASIC INSTALLATION:

I. Tools

A. Cement Mixer (3 cu.ft. capacity)

B. Wheelbarrow (s)

C. Iron-tooth rake to spread rock to approximate thickness

D. Trowel (for finishing of product)

E. Propane Torch (to remove any moisture)

F. Hammers

G. Chipping Gun (plane down concrete at thresholds)

H. Tapcon Drill and Tool

II. Forming Materials

A. Forming Stakes

B. 1” x ___ (wood forms) for over pours and steps.

C. Cantilever forms (pool edges).

D. Form Release (to keep product from sticking to forms)

E. Tapcon Screws.

III. PREPARATION FOR DECK

A. Must be clean and dry

B. Follow existing expansion joints accordingly

C. Remove spoiled or flaking concrete

D. Build up or channel low lying areas for necessary drainage

E. Asphalt or wood surfaces must have coat of epoxy applied prior to installation of

river rock

IV. FORMING

A. Wrap product around edges of deck that can be seen.

B. Apply light coat of epoxy to vertical edge of substrate.

FORMING PROCEDURES:

Place forming stakes against edge of vertical substrate; this will space out from existing edge allowing product to fill in void between existing edge and form. Place pre-waxed form against stakes and install forming stakes to hold form in place.

FOR STEPS:

Follow above procedure except fasten form with tapcon or concrete nails. While installing river rock, remove spacing stakes as the river rock fills voids. Trowel top to smooth finish and level edge.

FORMING OF CANTILEVER EDGE:

Place a row of duct tape on pool tile. Top edge of tape should follow top edge of pool tile. Apply double face tape to foam then extender to the opposite side of the tape. Apply form adhesive to foam backing and glue backing to extender. Install concrete nails in concrete approximately one foot from edge of pool and space nails about every two feet around pool. If pool has straight edges use strips of 1x2 wood. If pool has curved edges, use strips of 2” masonite. Drill holes through wood backing. Place above mentioned backing strips against foam backing, pull tight and tie wire to nail. After river rock is installed and hard, remove forms and cut tie wires even with rock edges. River rock dace needs to be ground slightly to smooth edge. After grinding anddust has been removed, apply light coat of epoxy to surface that has been ground.

V. MIXING OF MATERIAL

A. Epoxy has a set mix ratio (do not vary). Mix three (3) equal parts resin to one (1)

equal part of cure. Mix vigorously for at least two (2) minutes.

B. Place correct poundage of desired pebble in cement mixer and add mixed epoxy.

C. Let epoxy and stone mix until all stones have been covered with epoxy.

VI. FINISHING THE PRODUCT

A. Place river rock at place of installation

B. Spread evenly with rake

C. Trowel to a smooth finish. In order to obtain a smooth finish, trowel must be

occasionally cleaned with a proper solvent (Xylene, Trowel Slick, etc)

FINISHED PRODUCT SHOULD NOT BE WALKED ON UNTIL THE NEXT DAY!!!

CAUTION: Product should not be installed when temperature will not rise above 60°F. On such days, cold weather resin should be used.

What are River Rock Pebbles used for?

River Rock Pebbles are decorative natural stones designed to be used with Pebble Bond Epoxy to create a seamless, durable flooring system over concrete surfaces.

What surfaces can River Rock Pebbles be applied to?

When combined with epoxy, River Rock Pebbles can be installed over virtually any concrete surface, including patios, pool decks, walkways, driveways, garages, and interior spaces like basements or sunrooms.

What are the benefits of River Rock Pebbles with epoxy?

River Rock Pebbles offer several performance benefits when used with Pebble Bond Epoxy:

• Permeable surface that allows water to drain through
• Helps reduce runoff and supports drainage
• Slip-resistant for wet or high-traffic areas
• Weatherproof and durable in extreme conditions
• Low maintenance and easy to clean

Are River Rock Pebbles good for pool decks and outdoor areas?

Yes. River Rock Pebbles are commonly used around pool decks, patios, and outdoor living spaces because the system helps eliminate standing water and provides a slip-resistant surface.

How does the permeable design work?

The River Rock system allows water to pass through the surface and follow the natural runoff of the existing structure, helping reduce pooling and drainage strain.

How durable is a River Rock Pebble epoxy system?

The combination of natural stone and epoxy creates a long-lasting, weather-resistant surface that can withstand heavy use and harsh environmental conditions.

Is River Rock Pebble flooring slippery?

No. The textured surface of the stones provides natural slip resistance, making it ideal for wet environments like pool decks, walkways, and outdoor showers.

How thick should River Rock Pebbles be installed?

Typical installation thickness is:

• 1/2 inch for patios, pool decks, and walkways
• 3/4 inch for driveways

How much area does River Rock Pebbles cover?

Coverage depends on the mix ratio, but a common application uses approximately 3 bags of stone per 1 gallon of epoxy, covering approximately 35 square feet. For additional questions on coverage reach out to us at 630-675-4509 or [email protected].

Is River Rock Pebble flooring easy to maintain?

Yes. The system is low maintenance, long-lasting, and can be cleaned easily, making it a practical choice for both residential and commercial applications.

Where can River Rock Pebbles be used?

River Rock Pebbles are suitable for a wide range of applications, including:

• Pool decks
• Patios and porches
• Walkways and stairs
• Driveways and garages
• Commercial spaces and showrooms

Can River Rock Pebbles improve uneven concrete?

Yes. The system can be applied over uneven or damaged concrete to create a uniform, attractive surface while protecting the substrate.

Pro Tip

For best performance and drainage, ensure proper surface prep and maintain the recommended thickness (1/2”–3/4”). This helps maximize permeability, durability, and long-term appearance—especially in high-moisture areas like pool decks and patios. Ensure River Rock Pebbles are clean and dry before applying.
